Time-resolved spectroscopy in the Rijnhuizen Tokamak Project tokamak
Fusion Engineering and Design, 1997Abstract At the Rijnhuizen 'rokamak Project tokamak spectrometers are used to diagnose the velocity distribution and abundances of impurity ions. Quantities can be measured as a function of time, and the temporal resolution depends on the line emissivity and can be as good as 0.2 ms for the strongest lines.

A new operational regime has been observed in neutral-injection-heated ASDEX divertor discharges. This regime is characterized by high ${\ensuremath{\beta}}_{p}$ values comparable to the aspect ratio $A({\ensuremath{\beta}}_{p}l~0.65A)$ and by ...

17th IEEE/NPSS Symposium Fusion Engineering (Cat. No.97CH36131), 2002
The KSTAR (Korea Superconducting Tokamak Advanced Research) project is the major effort of the Korean National Fusion Program to design, construct, and operate a steady-state-capable superconducting tokamak. The project is led by Korea Basic Science Institute and shared by national laboratories, universities, and industry along with international ...

Journal of Plasma Physics, 1988
Large-aspect-ratio tokamak equilibrium is studied, including effects, such as ellipticity of the flux surfaces, of second order in the inverse aspect ratio. To facilitate the interpretation of experimental data, the analysis uses simple coordinates that are readily evaluated, rather than co-ordinates based on the exact flux surfaces.

Physics of Plasmas, 2004
Analytical treatment of magnetic islands with high poloidal mode numbers and widths smaller than ion Larmor radius (microislands) is presented. The profile functions and rotation frequencies of microislands in the scope of the standard two-fluid magnetohydrodynamics are investigated.

Tokamak to tokamak variation and collinearity in scaling laws
Nuclear Fusion, 1990The large multiplicity of scaling laws which almost fit the data is associated with the near degeneracy of the data covariance matrix. The traditional analysis assumes that only discharge to discharge variations are important. Using Swamy's random coefficient model, tokamak to tokamak variations are included in the statistical analysis.

Nuclear Fusion, 1984 Impurities continue to be a concern for future fusion devices, and ongoing efforts are made to study their generation, confinement, and control. Techniques for analysis of concentrations, power losses, and confinement of impurities are surveyed, and experimental examples illustrating typical observations in tokamak plasmas are presented.

Fusion Technology, 1998
From a discussion of fusion reactor designs based on today`s well-established experience gained in the operation of large tokamaks, it is concluded that such reactors are economically not attractive. The physics involved in the various options for concept improvement is described and the main experimental results of current research are shortly ...

Plasma Physics and Controlled Fusion, 1988
The evolution of tokamaks is described, concentrating on Soviet research. The author deals with internal disruptions, fan instability, neutral beam injection, ICRH, ECRH, profile consistency, current drive, bootstrap current and the physical evolution of the Tokamaks themselves.
